Excretion of various glycosaminoglycans in patients with chronic duodenal ulcer

Abstract: Excretion of individual glycosaminoglycans (GAG's) with urine was studied in patients with chronic duodenal ulcer. 31 patient with acute manifestations of the duodenal ulcer, 24 patients within the period of remission as well as 29 practically healthy persons were studied. Column chromatography on cellulose was used for separation of a mixture containing keratan sulfate, hyaluronic acid, heparan sulfate, chondroitin-4 and -6-sulfates, dermatan sulfate and heparin. During the acute period of duodenal ulcer daily excretion of all the individual GAG's with urine was decreased (especially distinct for the fraction of chondroitin-6-sulfate) as compared with excretion of these carbohydrates in healthy persons. The level of GAG excretion was increased distinctly, exceeding the values found in healthy persons, during the remission. Excretion of chondroitin-6-sulfate and keratan sulfate was markedly increased in these cases.
